This Is How I Mastered TypeScript Like I'm 5 (And How You Can, Too!)(5)

This chapter is part of a 20-chapter series on mastering TypeScript, and it's recommended to read the previous chapter before continuing. This chapter focuses on union and intersection types in TypeScript. Union types allow a value to be one of multiple types, denoted by the "|" symbol. For example, "let value: string | number;" means the value can be either a string or a number. However, when using union types, you need to be careful about the methods you use, as not all types in the union may have the same methods. Intersection types, denoted by the "&" symbol, combine multiple types into one. For instance, "type TSDev = Person & Coder;" means a TSDev is both a Person and a Coder. Union and intersection types allow you to "mix and match" types in TypeScript. This chapter provides a basic understanding of these concepts, and the next chapter will cover type narrowing.
